To all whom z't may concern:

Be it known that we, THOMAS A. Conni` MAN and PETER Vunonueunoiir, Jr., citizens of the United States, residing at the town of Vredenburgh, county of Monroe, and State of Alabama', have invented a certain new and useful improvement in Marking- Machines, of which the following is a full,

clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence lbeing had to the accompanying drawings, forming part of this specification.

This invention relates to a machine flor mechanically marking the 'ends or edges of lumber or similar material.' c,

rllhe'principal object of the invention is to provi e a device whereby lumber may he marked, as with a grade mark or a trade niark, during the course of its manufacture, and without necessitating its heing reliandled especially for the marking operation.

Another object oi the' invention is to provide a machine for marking lumber or simi lar material, which is. in eiiect automatic in that it requires no special operator, its function being exercised in conjunction with the operation oi' other machines employed inthe manu-facture of the lumber.

Another objectoi our invention is to provide a device for marking lumber which may he used in conjunction with the machine commonly movvn as a trimmer.

A further object is to provide a marking machine which is adapted for use with trimmers already installed or in operation.

A. still further object is to provide a marking mlachine of the sort which has a large output capacity.

Another object is to machine by which a mark may he either printed, pressed or burned upon the lumber as may be desired.

A still further object is to provide a mark ing machine of the sort specilied which may be rendered inoperative for a desired period upon the omission of a selected tion or step in the manufacture oi the luinloer..

A further object of our invention is to provide special operating devices of novel 'l I that before ledges of boards are dressed, which would iiurthermore,

spitled previos a marking prior opera- Oth er and further objects of our invention will be obvious or pointed out hereinafter. here is a growing demand iii the lumber manufacturing trade for a successful and ecient device for marking lumber durin its course of manufacture with any desirecgl trade mark or grade mark. Various devices heretofore attempted have not proved acceptable to lumber manufacturers either from cost of operation, due to their requiring special handling of the lumber, inaccuracy in operation, or slowness.

fl. machine which will successfully mark the ends of boards has a greater utility than one which is designed to operate upon only the sides or edges of boards, 'for the reason use vin most cases, the sides and remove a mark placed on those parts, and the sides and edges must he kept smooth and uninarr'ed in order to maintain the grade of the lumber.

The device constituting our present invention is designed to meet all of these various requirements for a successful marking machine, and to secure the desired result in an economical and edicient manner.

ln the accompanying drawings, we have shown for the purpose of illustration, varions forms or our invention, including divers forms and modifications of various parts thereof..

From the Jforegoing, it will be observed that our invention contemplates a form of device which may be operated in conjunction with the operation of a machine universally employed in the manufacture ot lumber, and that, therefore, the use of our device does not necessitate special handling of the material or any special manual operation to secure the intended results.- Furthermore, it is obvious that the speed of oli' the device is limited onl the revision oi' means for positively and holding the material to the action 0i" the marking Wheel, and due to the arrangement whereby theniarkingl device may be Withdrawn from ity might oder obstruction, the operao device is certain, accurate, safe and economical. Furthermore, dus to the t that the marking device is complete in itseir,
